Actually the only person I see Gin-san with. And their relationship is NOT father/daughter. Gintoki as a father? LOL. And we all know that Kagura doesn't see Gintoki as a father/brother. Some episodes show that. Just give her 4 years.

...Ill say Otae-Kyuubei then, Gintoki-Kagura, Katsura+that married woman, Okita+i dunno may fit with the M ninja, Kondo+Either the gorilla or the screwdriver person or bacterium ballus, Shinpachi+no one, just cause there really doesn't seem to be anything that work for him but that idol person which im certain won't happen, or maybe that cat-ear person who tried to scam/rob him.

and tadaaaaa~! here are the yaoi pairs possible! don't you dare open this if you despise yaoi. i don't want to see comments like yaoi sucks, yaoi is eeew or whatever bad reactions. mind your own buisness, okay?

Spoiler Alert! Click to show or hide

♥ hijikataXgin-chan (do i need to explain this? i mean it's really obvious. many consider them as a pair. there are even episodes that gives hint about this pair.)

♥hijikataXokita (well they do fit each other but since okita really does look good w/ kagura, it's a no-no to me)

♥yamazakiXshinpachi (eeep jimiXjimi LOL)

♥gintokiXkatsura (they are friends since childhood and they sometimes hangout together and remember episode 50 -if i'm right- where zura became a singing actress w/ gin-chan?)
